AUTOMATIC SWINGING GATE.

SPECIFICATION forming part of Letters Patent No. 350,189, dated October5, 1886.

Application filed December 26, 1885.

To all whom) it may concern.-

Be it known that I, SAMUEL L. DENNEY, a citizen of the United States,residing at Gap, county of Lancaster, and State of Pennsylvania, haveinvented new and useful Improvements in Automatic Swinging Gates, ofwhich the following is a specification.

My invention relates to improvements in auto matic gates, whereby iseffected the changing of the gate from a true vertical to an inclinedposition at the same time with the lifting of the forward end of thegate, thus causing it to swing by its own gravity open or shut, asdesired. I attain this object by the mechanism illustrated in theaccompanying drawings, in which Figure 1 is a front elevation of thegate closed; Fig. 2, a perspective view of theringbracket with ring;Fig. 3, a ground plan of the ring-bracket; Fig. 4, a side view of theringbracket; Fig. 5, a ground plan of the ring; Fig. 6, a side view ofthe ring, showing a roller; Fig. 7, a ground plan of the resting-plate;

Fig. 8, a side view of the same; Fig. 9, a view of the lower upright ofthe gate and the back post partly in section; Fig. 10, a front view ofthe stop with its notch; Fig. 11, aground plan of the same; Fig. 12, aView of the front part of the gate partly in section; Fig. 13, a view ofthe gate opened; Fig. 14, a view of the gate lifted, ready to be opened;and Figs. 15 and 16, views of the shaft in two of its positions.

Similar letters refer to similar parts throughout the several views;

The gate A is constructed, in the usual way, with heel and front posts,having horizontal rails r s r tenoned into said posts, with a suitablenumber of crossed or other vertical rods to give an ornamentalappearance to the gate.

Usually in constructing gates to swing automatically open and shut avertical shaft with a crank at one end to receive the eye secured to theheel of the gate is employed to throw the gate out of its true verticalposition,and at the same time lift the front end slightly to disengagethe latch from the catch on the post against which the gate closes.

By my improved means for canting and lift- Serial No. 186,814. (Nomodel.)

ing the gate I change simultaneously both ends of shaft H, causing themto move in opposite directions. This I accomplish bymeans of the rings hh, Figs. 2 and 5. These rings, as will be noticed, fit loosely intoring-brackets b 1), Figs. 3 and 4, which are bolted firmly to thegate-post B. Said rings are provided with anti-friction rollers t 15,thus securing great freedom of action in working the gate. These ringsare secured to the shaft H, and are set reversely to each other, thusgiving to the shaft the requisite inclination by a comparativelyshortcrank movement, and thereby securing great leverage and easy controlover the gate when opening and closing. The lower eyebolt, 9, secured tothe gate, is made to exceed the upper one in length by the innerdiameter of the ring 71, as is evident from the drawings. Shaft H isinserted in a socket, F, in which its lower end moves freely. Saidsocket is pro- .vided with suitable jaws to receive a roller, f,

which rests on plate J, which is bolted to the gate-post B. A pin, 00,projects through said shaft, immediately above the projection 12 on ringh, upon which the eye 57, secured to gateheel a, rests. Thus it will beseen-the weight of the gate is supported by plate J through its sup portupon the pin above the ring, whereby the latter is left free to workwithout any downward pressure or strain upon it.

To the upper end of shalt H is secured crank q, to the outer end ofwhich rod R B, Fig. 13, is connected. Said rod is connected to levers nn, which are pivoted to posts N N. Thus it will be seen that by drawingthe righthand lever away from the gate the position of the shaft will beinstantly reversed to that shown in Fig. 16, and the gate will be liftedto that shown in Fig. 14 and will swing open, and by retaining hold ofthe lever until the gate has swung round to the line of the lever-rodand then releasing .it the front end of the gate is let down upon therest 0, which relieves the gate-post wholly from the weight of the gate,whereby the post is prevented from sagging.

I use a spring-bolt, m, for securing the gate in its shut position,which slides endwise in a mortise formed in the face of post a, andslides into the open slot formed in catch 0, out of I 2. The combinationof the gate Afvertical which slot the bolt is lifted in the movement ofopening, as seen in Fig. 14.

What I claim as my invention, and desire to 5 secure by Letters Patent,is

1. The combination, in an automatic swinging gate, of the gate A,vertical shaft H, rings 7 h h, ring-brackets b b, I'OHGI'zSOCkGt F,roller f, plate J, and crank q, substantially as set IO fonth.

shaft H, rings h, ring-brackets b,socket F, roller f, plate J, crank q,rod R, and lever n, substantially as described.
